Refraction spear fishing
WebThis PowerPoint introduces the reflection of light including the concepts of the refractive index, angle of refraction, Snell's Law, total internal reflection, as well as real life phenomenons that include the refraction of light such as how diamonds sparkle and how it affects spear fishing. WebThis PowerPoint is a unique way of teaching light refraction by using spearfishing as an example. Your students will never think of fishing in the same way again.Learning intention: To explain how Indigenous Australian people use their knowledge of the refraction of light when spearfishing. Success criteria: Students will view the PowerPoint …
